DIY Powerful Solder Fume Extractor

Hi all ,On this Instructable will show you how to create a powerful diy Solder Fume Extractor with dual fans, this project is completely made out from scrap.You know what? breathing solder fumes is dangerous to health!How many of you are aware of lead poison?

"Lead is used in the soldering process in the form of lead/silver filler metals. When heated, lead oxide fumes are formed. Excessive exposure to lead oxide fumes can result in lead poisoning. Symptoms include loss of appetite, indigestion, nausea, vomiting, constipation, headache, abdominal cramps, nervousness, and insomnia. Lead is absorbed through the mucous membranes of the lung, stomach, or intestines and then enters the bloodstream"

This simple project can solve those problems,here working is divided into two section the larger fan will absorb all fumes into filter and smaller fan will pump out filtered fume you can drive out using pvc pipes.Please go threw all picture for better understanding .

Supplies:

Step 1: Parts List

An empty can

Large fan

Small fan

Led (optional)

Sponge to filter denser fumes (prefer thicker one ,the one i used has 1inch thickness)/Use carbon Fume Extractor Filters for better result.

Power switch

Potentiometer (to control fan speed/ on and of)

Any type of dc connector (both male and female)

Glue

12v power source (can be batter or wall adapter)

Step 2: Making the Case

Mark dimension of small fan on the bottom , and cut threw it

Luckily my larger fan fit at open side of the can .

Make holes where you wanna place switches

Cut sponge to the same dimension of the can.

Step 3: Assembly/ Wiring

Fix the small fan

Add and connect female dc jack with potentiometre

Glue the sponge at middle of the can

Add led strip

Place the switch and do all the connection

Hot glue and seal larger fan on top.

Circuit is provided at last image of this step.

Step 4: Done!!/ Video

Hooray! now i can stop inhaling all deadly fumes while soldering ,this guy is so aggressive and working so efficient.

I believe you quoted this from a dubious source.: "Lead is used in the soldering process in the form of lead/silver filler metals. When heated, lead oxide fumes are formed. Excessive exposure to lead oxide fumes can result in lead poisoning. Symptoms include loss of appetite, indigestion, nausea, vomiting, constipation, headache, abdominal cramps, nervousness, and insomnia.

--> The temperatures used in soldering are not sufficient to vaporize lead. There is ZERO lead in soldering fumes. Still harmful, but no lead.

Hi I am going to need to put extra suction piping on this so as to get it far away from the neighbours window (I don`t want them breathing this stuff either!) How far should I leave between additional motors to keep the flow going? Thanks.
